Since it was an old movie, a lot of style sucked... but hey! What were we supposed to do back then?
I agree that overall this is an awesome movie. No violence is that strong (because it's old, they had to use the light-hitting technique which is extremely visible) and the word "d--n" is probably said 5 times but no one really cares.
It's midly amusing, but I can't think of anything else positive to say about this movie for a 7 year old. Violence, bad language, and crass product placements abound. The overwhelming message is that the world is a bad place, the police are useless, and you'd better know how to fight. We turned it off within 10 minutes, during the second scene of rather brutal person-on-person violence.
